2 - SQRF4J20C ENGINE OK (a) Remove Engine Control Module (ECU) from malfunctioning vehicle. (b) Install a new engine control module to malfunctioning vehicle. OK Repair or replace new module NG (a) Connect diagnostic tester and clear DTCs. (b) Run the vehicle as specified procedure. The operating way should meet the conditions for corresponding fault diagnosis. (c) Read the fault information and confirm that the fault has been solved. OK Conduct test and confirm malfunction has been repaired ■ Ambient temperature sensor circuit voltage too low / too high ■ DTC Confirmation Procedure Confirm that battery voltage is not less than 12 V before performing following procedures.

• Turn ENGINE START STOP switch to OFF. • Connect the diagnostic tester (the latest software). • Start engine and warm it up, and then read DTC again. If DTC is detected, malfunction is current. • If DTC is not detected, malfunction is intermittent. Hint: When performing circuit diagnosis and test, always refer to the circuit diagram for specific circuit and component information.
